From d9a9174fa5687521035b2ec82cce86cdcf4f36e6 Mon Sep 17 00:00:00 2001 From: Alex Marginean Date: Tue, 16 Jul 2019 11:21:17 +0300 Subject: drivers: net: driver for MDIO muxes controlled over I2C This driver is used for MDIO muxes driven over I2C. This is currently used on Freescale LS1028A QDS board, on which the physical MDIO MUX is controlled by an on-board FPGA which in turn is configured through I2C.
